To @ZZ whom it may concern.: v.

Be it known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen ofthe United States, have invented a new and useful Improvement in Nail Making, Distributing, and Driving Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification,A

It also relates to the employment, in connec' tion with a mechanism formaking or deliveringa gang of fastenings, of a gang of clearers for forcing or feeding the fastenings through the passages of the distributer into the fastening-carrier or holes or passages from which the fastenings lare driven and for clearing said passages.

In the drawings, Figurell is a view in vertical central section of a machine having the features of my invention. Fig. 2 is a View in cross-section thereof. Fig. 3 is a view in side elevation of the machine, representing the position of the parts when the clearers are elevated. Fig. 4 is a View in elevation of the same parts, representing the position of the parts when the clearers are depressed. Figs. 5 and 6 are detail views. Fig. 7 illustrates the connection between ,the nail-making devices and the nail-driving devices. Fig. 8 is a view representing the nail-feeding plate, hereinafter referred to, made of different thicknesses to feed wires differing in gage or thickness.

In the drawings, A A represent the dierolls. Instead of being upon a horizontal line or plane, as shown in the patent above referred to, they are placed upon avertical line or plane--that is, one over the other-s0 that the .gang or group of Wires from which the fastenings are made are fed horizontally instead of vertically. The rolls preferably are of a sufficient length to enable a large number of nails or fastenin gs to be made, and in the drawings I have represented them as adapted to make thirty nails simu1taneously. The rolls have end bearings in suitable boxes held or supported by the frame B, and the boxes of the upper roll are adjustable in relai; tion to the boxes of the lower roll by means of adjusting-screws a. lThe rolls may also have central bearings or supports a?. The rolls carry or support point-formin g dies asathe roll A the sections a3, and the roll A the sections CL4. The dies preferably are made or formed in groups of two or more from one plate or block. In other respects they preferably are like those described in said patent.

The cut-off devices comprise aout-off plate C and the pressure-plate C. The cut-off plate C extends the length of the dies carried by the rolls and may be in one piece; or if the rolls have a central bearing it maybe in two pieces, one upon each side of the central bearing. The bearing-plate C is of similar shape and arrangement.

The cut-off plate C is represented as operated or moved readily by stationary or adjustable cams c and the push-rods c. (See Figo.) The pressure-plate C is moved outward by means of the springs c2. The arrangement of the dies, cut-off, and presserbar is similar to that described in the said patent and in the patent, No. 375,209, to C. C.

Small, with the exception that the dies are placed closely together, and the cut-off bar and presser-bar are continuous instead of being made in separate pieces.

The devices for feeding the wires comprise feed-bars D D, set in recesses in the rolls A A', respectively, the roll A having the longitudinal recess d in its periphery of a Width sufficient to receive the widest feed-bar which it may be necessary to use, and the roll A having the recess d for receiving the corresponding feedbar. vided, preferably, with rough or corrugated surfaces d2, and they are of the length of thev parts of the rolls-that is, they are long enough to 4include all the dies. ing is provided the rolls, they may be made in two parts, or, in fact, they maybe madeof any number of parts. vThey are fastened tov the rolls, preferably, by screws, and in a manner to be easily removable therefrom, and the edge cl3 of each, when attached to its respective roll, is in contact with the shoulder d4, formed The feed-bars are pro? Vhere a central bear-A IOO by the recess. The width of the surface of the feed-bars determines the extent of feed of the wires over and above that caused by the drawing and feeding action of the dies a3 ai. To make a short-pointed nail, the feedbars maybe entirely dispensed with. To make short unpointed nails, the dies may be dispensed with and the feed-bars D D substituted therefor. To vary the length of the fastenings or nails, it is simply necessary to vary the width of the feed-bars by removing one set and substituting a narrower or wider set for those removed. To vary the length of each gang of fastenings, the feedebars D D are made of ditt'erent widths, and one thus formed is represented in Fig. (i. By thus varying the width of the feed-bars each gang or group of nails may vary in length to any desired extent. A portion of them may be long and others short. By varying the thickness of thefeed-bars wires of different thicknesses or gages may be simultaneously fed and acted upon by the single pair of rolls, so that some fastenings may be made of one length and one gage, while others may be simultaneously made of a different length and of a different gage. y (See Fig. S, which shows section of feed-wire.)

In operation the wires a are fed from reels (not shown) through throats or passages e in a plate or block E to the dies, there being a separate hole e for each wire and die, and the point or end of the block E preferably is brought as closely to the converging point of the rolls and dies as possible. There may be placed in front of the block E the guiding rolls e' e2, between which the wires may run to the passages or holes e, and one of them preferably has an elastic covering of rubber e3, and is set with some slight tension against the roll e2 sutlieicnt to prevent the wires from drawing by gravity out of position from between the rolls, but not sufiicient to create any appreciable tension on the wires. By arranging the feeding devices upon the die-rolls instead of separately, as in the patents referred to, these important advantages are obtained: First, the wires are relieved of undue tension, whereby each pair of dies acts in a measure independently of the other, so far as drawing the wire which they act upon; second, the feeding' of the wires is more uniform and is at the same time capable of far greater variation; third, the construct-ion is much cheaper and simpler. The fastenings are delivered from t-he rolls into the passages F, there being preferably a passage for each nail or fastening. These passages are represented as curved sufficiently to permit the fastenings to fall by gravity into the vertical passages f These vertical passages,\vith the curved passages F, are preferably formed in a removable block, and the upward extensions f2 of the passages f provide guides. for the clearers G, there being a clearer for each passage j These clearers are of a length to extend through the passages f and the passages hin the distributerll. The distributor II is like that shown in the patent referred to, and comprises, in substance, the lower block 7L', in which the lower ends of the tubes h2, forming the passages h, are secured, and which block has holes in continuation of said passages h, the said tubes h2, and the upper block h3, which holds the upper ends of the tubes, and which has holes opening into thc pas sages h and in line with the passages f.

The clearers G are made, preferably, of spring-wire or piano-wire, and are attached or secured at their upper ends to a slide g, which is givenl a vertical movement in the vertical guides g at a suitable intervalthat is, after the gang of fastenings have been made and delivered into the passages j by means of one or more cams g2. In the drawings there are two cams represented, one at each end of the upper roll A, levers y, links y", and levers gpivoted at g to brackets y? and connected at their upper ends by short links gS to the slide IVhiIe I have represented two sets of links and levers, I would not be understood as limiting myself thereto, as one set only may be used; neither would I confine myself to this method of operating the slide. The clearcrsG, traversing all the passagesj" and h into which nails or fastcnings are fed, insures the proper delivery or feeding of the nails or fastenings through said passages to the carrier or other receptacle M, and they also insure the lclearing of the passages, so that there can be no clogging, and they are always in condition to receive the next gang or group from the nail-supplying devices.

I have representedthe fastenings or nails as delivered to a carrier M, and this carrier is movable, preferably, by means of the cam m, to transfer the nails to the driving devices, comprising, preferably, a tcmplet m and a gang of drivers m2. In operation the wires are led from the reels into the passages eand to a position between the rolls A A', and upon the rotation of the rolls, after, of course, the ends of the wires have been severed, the wires are simultaneously fed, point-forming sections formed in the wires, and the previously-pointed sections severed and delivered to the passage f', irbm which they are fed through the tubes of the distributer by the clear-ers G. Of course, as a rule, the rolls A A make but one revolution-that is, one complete revolution of the roll points and severs a gang of fastenings, feeds the wires, and affords time for the operation of the clearers. As above stated, fastenings varying in length can be simultai'ieonsly made and delivered. Of course the feed-blocks D D may be formed integral with the rolls A A but it is a much betterconstruction to make them separate or independent of the rolls, as above specified.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United Statesl. The combination of devices for simul- IOO IIO
